LEVER-BUCKLE.

SPECIFICATION forming part of Letters Patent No. 309,730, dated December 23, 1884-.

- Application filed July 14, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN A. MUNDY, of Syracuse, Onondaga county, State of New York, have invented certain new and useful Improvements in Lever-Buckles, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a top or plan view and an elevation, partly in section, of the buckle closed. Fig. 2 shows a plan view and side elevation of the finger-lever; Fig. 3, like views of the upper body-plate; Fig. 4, like views of the lower body-plate, and Fig. 5 a side elevation of the buckle partly open.

My invention relates to the class of leverbuckles that are operated by a spring-seated finger-lever, and which are used in combination with a looped adjustable draw-plate to produce tension of fastening.

binations of elements hereinafter specifically set forth in the claims.

It is constructed as follows: A is the fingerlever, constructed of sheet metal and struck up to about the shape shown in the drawings, except that at first the barrel a is left partly open, to be closed, as hereinafter explained. Upon each side of this lever I construct an outwardly-projecting ear orspur, 1), (shown in the drawings as rectangular but the shape can be varied.

The body proper of the buckle is made in two parts-an upper plate, B, and a lower one, C-either or both of which may be constructed from springy sheet metal, and when one is formed of such metal the other may be made from ordinary stii't metal. The plate B is usually of about the form shown in the drawings, having a rearward tang, in which I punch a rivet-hole, c, and having front arms, (I, one on each side, inclosing the space g on three sides. The plate C is of about the form shown in the drawings, with a rearward tang, in which I also punch a rivet-hole, and the front arms, 0, of which plate are connected by the cross-bar h, which'bar may be integral with the arms a, or secured to them in any ordinary manner the arms andbar wholly inclosing the space The strap by which the 5o body of the buckle is attached to the shoe It consists of the several devices and cominclose the tangs of the plates, and secure it.

passes through the spaces 00 y and covers the tangs of the plates. The rivet -holes in the plates should coincide when the plates are placed upon each other, so that they can be riveted together in their proper relative positions.

I connect the finger-lever A to the plate C by closing the barrel c around the bar h loosely, with the ears I) lying under the arms (Z of the plate B. I

D is the slotted draw-plate, constructed in the usual 1nanner,with side bars, at, connected by crossbars 0, the slots freely receiving the lever A.

The buckle is operated as follows: I connect the body of the buckle to itsholdingstrap in the ordinary manner by passing the end of the strap through the spaces a: y in the plates B C, and bend the end back, so as to I then connect the draw-plate D to an opposite strap in any ordinary way. I then pass the finger-lever A through one of the slots in the plate D, the lever being thrown forward for that purpose, and when the lever is next thrown back the ears I) soon begin to wedge between the plates B C, and as the movement of the lever backward continues the cam action of the ears springs the plates farther apart until the center of the movement of said cars is reached, when,as the movement of the lever continues,the spring action of the plates will throw the lever down to and hold it in the position shown in Fig. 1, at thesame time drawing the plate D over and tightening the straps to the desired tension. By this construction of a double plate body I obtain therein the desired spring action without using an yinserted flat or coil spring. The plates B C can be punched out in one piece and their ends then bent over upon each other.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A lever-buckle consisting of two superimposed plates, one provided with arms d, and the other with a bar, h, and a finger-lever connected to one plate, so as to swing thereon, and having spurs b, that bear upon the opposite plate, substantially as described.

2. Alever-buckle constructed with the le- ICO ver A, providedwith barrel a and spurs b, the slotted draw-plate D, all connected and operplate 13, provided with arms (Z, and the plate 0, ating together substantially as and for the provided with arms 0 and cross-barh,said plates purposes specified.

I V T T r 3. Alever-buckle constructed with the le- JOHN MLADX' ver A, provided with barrel a and spurs b, the In presence ofplate B, providedwith arms (I, the plate 0, C. XV.
